Abstract

L'invention concerne un pointeau motorisé pour circuit frigorifique. Le corps du pointeau (1) comporte un conduit du réfrigérant (41) qui réduit le débit du réfrigérant s'écoulant par un circuit d'écoulement du réfrigérant (9) vers un espace intérieur (30) d'un boîtier (3) à travers un dégagement (17) d'un insert du pointeau formé entre l'orifice (16) de l'insert du pointeau et une aiguille (2) insérée dans ledit orifice (16). Lorsque le réfrigérant s'écoule à travers le dégagement (17) de l'insert du pointeau en fonction d'une montée ou d'une baisse de pression du réfrigérant, la boue mélée au réfrigérant qui adhère à la surface de la paroi du dégagement (17) de l'insert du pointeau peut être éliminée par le conduit du réfrigérant (41) en quantité équivalente à une quantité réduite du débit du réfrigérant. On empêche ainsi autant que possible une adhérence de la boue due à un fonctionnement irrégulier de l'aiguille (2), ce qui garantit un fonctionnement normal de l'aiguille (2).
